Hello there, it’s me again, with problems again. Note: I’ve installed XFCE Desktop version on my BBB’'s eMMC.
I think my eMMC got corrupted when a classmate tried to power a 5" XPT2046 LCD from the BBB’s USB port and then, as the screen was not working, he just unplugged the BBB’s 5V jack instead to hold the power button until shutdown
The problem is now, when I try to start the BBB with the LCD screen connected via HDMI (but being the LCD powered by a laptop USB port), all I see is the Linux penguin, and then the BBB shutdowns and restarts, and does this in an infinite loop. The only way I could use it again with the LCD as screen was modifiying the uEnv.txt in the line that says:
#In the event of edid real failures, uncomment this next line: #cmdline=coherent_pool=1M net.ifnames=0 quiet cape_universal=enable video=HDMI-A-1:1024x768@60e
I had to modify the resolution to 800x480 to match my LCD screen’s resolution.
Then, from so on, every time I want to turn on the BBB and use it with the LCD, I have to:
Unplug everything from the BBB, connect it to a 5V power supply, so it powers in
Wait several minutes and then connect the LCD
Is my eMMC corrupt? Can I fix it?
